Doctor Allegedly Deleted ‘Critical Decimal Point’ From Medicine Dosage — Toddler Died As A Result, Lawsuit Claims

A family is suing a University of Florida (UF) hospital after a doctor allegedly deleted a critical decimal point from a medicine dosage, resulting in the death of her two-year-old son, according to a Nov. 6 lawsuit.

The family is suing UF Health Shands Children’s Hospital for alleged wrongful death medical negligence following the death of Dominique Page’s son, De’Markus, according to the complaint. In March 2024, De’Markus was a patient at AdventHealth Ocala Hospital and was later transferred to UF Health Shands Children’s Hospital.

De’Markus had been diagnosed with rhinovirus/enterovirus and was found to have a low blood potassium level before being transferred to UF Health Shands Children’s Hospital. De’Markus was also suspected of having autism, experienced minor speech and developmental delays, and remained underweight due to being a picky eater, which made him more susceptible to illness and impacted his care, documents show.

According to the same complaint, a doctor at UF Health Shands Children’s Hospital allegedly entered the incorrect dosage for De’Markus’ oral potassium phosphate medication. De’Markus was initially prescribed 1.5 mmol of the medication to be taken twice a day, but a missed decimal point allegedly resulted in him receiving 15 mmol, or 10 times more than the previous dosage. The complaint accuses Dr. Jiabi Chen of entering the incorrect dosage.

In addition, the complaint alleges none of Chen’s supervising colleagues caught the mistake and canceled the order despite a Red Flag warning in the hospital’s pharmacy system alerting them to the incorrect dosage. The lawsuit claims De’Markus “received two consecutive doses of a massive overdose of oral potassium phosphate,” and his potassium rose to a fatal level, which allegedly resulted in a hyperkalemic cardiac arrest, at least two to three botched intubation attempts, and his eventual death.

Jordan Dulcie, the family’s attorney, told Law and Crime the child’s death was “entirely preventable.”

“No parent should have to lose a child like this,” the attorney said.

“What this family has endured is unimaginable, and the worst part is that it was entirely preventable,” Dulcie added. “I’m committed to holding the University of Florida Shands Children’s Hospital fully accountable and presenting this case to a jury to avoid this tremendous grief from happening to another family.” (RELATED: Authorities Arrest 56 People In 3-Day Child Porn Sting Sweeping State)

The child’s mother also reacted to his death, calling her loss “extremely difficult.”

“It’s been extremely difficult since the passing of my son because to this day, I still have not known what happened. I was never told. When I asked, it was always vague; I do not know. I do not know. I still have nightmares about what happened,” Page told WCJB.
